Ok, the first problem I have is the truck stalls, and surges at idle. It only does it when you first start it up, if your rolling in gear, and touch the gas and release it again it will stall. Also when you come to a stop it will do it sometimes too.
Next thing is, my LC1 wideband shows lean spikes all the time, is this normal? I've only used this lc1 on my rear mount turbo truck, and it worked fine way back behind the turbo. I have the sensor mounted inbetween the header collector, and the cat, on the left bank. I just reset, and recaled the Lc1 last night, and it still does it.
It's my buddy's truck, 2000 silverado 2wd, LQ4 6.0L, 220/224 525/529 114 LSA, Thorley headers
